UPSETTlNG-IVIACHINE FOR PLOWSHARES.

SPECIFICATION forming part of Letters Patent No. 609,265, dated August16, 1898.

' Application filed February 24, 1898. Serial No. 671,534. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM A. CLARK, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Upsetting-Machinesfor Plowshares, of which the following is a specification.

The object of this invention is the prod uction of a machine forupsetting the unfinished plowshare along the edge thereof which is to bewelded with the landside in order to permit a perfect union of the twoparts and .to reduce the difficulty in welding.

In the drawings, Figure 1 is a plan view of this upsetting-machine. Fig.2 is a side elevation of the same. Fig. 3 shows the relative positionsof one of the upsetting-rollers and the share-holder. Fig. 4 representsby a plan view the portion of the share operated on after the operation.Fig. 5 shows the same in section.

Like letters of reference indicate correspondin g parts throughout theseveral views.

A is the supporting-frame of the machine.

B is the driving-pulley, rigidly mounted on the rotatable shaft B. B isa pinion, also fixed on the shaft 13.

O is a gear-wheel engaging with the pinion B which gear-wheel and thepinion O are rigidly secured to the rotatable shaft 0 D is a gear-wheelfixed on the shaft D. D are two face-plates, both fixed on the shaft Datopposite ends thereof and having wristpins D E is a sliding carriagecapable of a reciproeating movement lengthwise of the bed of thesupporting-frame A. E. are bearing-studs projecting from the sides ofthecarriage.

F are two connecting-rods extending between the wrist-pins D and thestuds E. I

G is an arm firmly secured to the forward side of the reciprocatingcarriage. G and G are two upsetting-rollers journaled in the arm G, nearthe forward end thereof, The former roller is grooved in its face inorder to give the edge of the share with which it is brought in contactan upward turn. It is followed by the smooth-faced roller G of adiameter slightly larger than the former,

. which further upsets the edge of the share.

operation by pressing the edge farther H is the share-holder, rigidlyattached to the bed of the machine.

' II are adjustable stops or gages to provide for the reception ofshares of different sizes. H is a screw-clamp for securing the share inthe holder H during the operation of the rollers G and G upon it.

I1 is a hand-wheel for operating the clamp H The movable member of thisclamp is recessed at H to provide for the reception of the plasticmetal, the form of the recess governing the shape of the upset. To thisupset the landside is welded, permitting a smooth and perfect unionbetween the share and the landside.

On account of the thinness of the usual share and the diiiiculty ofmaintaining it at a welding heat for a sufficient length of time on theone handand the danger of burning the metal by overheating on the otherthe welding of the share to the landside is quite a difficult operation,and when the weldingis accomplished the thickness of the share about theweld is considerably reduced. By upsetting the edge of the share agreater body of metal is brought together, reducing the difficulty ofthe operation and leaving its thickness unimpaired after the welding.

The operation of my machine is as follows: The share, formed to theproper size and heated to the proper temperature at the point to beoperated .on, is placed in the holder Hand secured in position by theclamp H The machinery is started and the carriage E thereby caused tomove toward the share. The roller G first engages the edgeof the share,giving that edge an upward turn. The roller G follows close behind andfinishes the back, completely filling the recess H and forming on whatis properly the under face of the share an upset portion of the formindicated by the dotted line in the view of the share shown in Fig. 4.

I claim as my invention- 1. In an upsetting machine, in combina tion, aholding device, a carriage capable of a reciprocating movement and agrooved upsetting-roller and a plain upsetting roller I00 journaled onsaid carriage, substantially as and for the purpose specified.

the upset desired, a carriage capable of a reciprocating movement, agrooved upsettingroller and a plain faced upsetting -roller j ournaledon the carriage, which latter upsetting-roller is of a greater diameterthan the grooved upsetting-roller, substantially as and for the purposespecified.
